Put doesn't upload the file to the ftp site

Question

Hi,

I have this piece of code in a web application:

srcFileName = "FileName";
destFileName = "DestFileName";
try
{
EnterpriseDT.Net.Ftp.FTPClient ftpClient = new EnterpriseDT.Net.Ftp.FTPClient("ftp.ftpsite.com");

String username = "username";
String password = "password";

ftpClient.Login(username,password);

ftpClient.Put(srcFileName,destFileName);

ftpClient.Quit();
}
catch (Exception err)
{
}

When I go to the web site, uploads the file to the ftp server successfully on the web server. But on other machines, the web application doesn't upload anything to the ftp server.

Could anyone please help me?

Thanks very much in advance.
